Manganese(III) porphyrin supported on multi-wall carbon nanotubes: A highly efficient and reusable biomimetic catalyst for oxidative decarboxylation of α-arylcarboxylic acids and oxidation of alkanes with sodium periodate

In the present work, the highly efficient oxidative decarboxylation of carboxylic acids and also the oxidation of alkanes with sodium periodate catalyzed by tetrakis(p-aminophenyl)porphyrinatomanganese(III) chloride, [Mn(TNH2PP)Cl], supported on functionalized multi-wall carbon nanotubes, MWCNT, is reported. The catalyst, [Mn(TNH2PP)Cl@MWCNT], was used as an efficient and heterogeneous catalyst for hydroxylation of alkenes with NaIO4 at room temperature, in the presence of imidazole as an axial ligand. Also, in this system, carboxylic acids were converted to their corresponding carbonyl compounds. This heterogenized catalyst could be reused several times without significant loss of its catalytic activity.
